In
philatelic terminology a Letter sheet, often written lettersheet, is nowadays an item of
postal stationery issued by a postal authority. It is a sheet of paper that can be folded, usually sealed, most often with
sealing wax in the
18th and
19th century, and mailed without the use of an
envelope. Letter sheets derive from the form in which written correspondence was made up before the mid-1800s when letters were written on one, or more, sheets of paper that were folded and sealed in such a way that the address could be written on the outside. They were literally a letter on a sheet (of paper).
